User interface
The reset values for these registers are device specific. Please refer to the Module Configuration section at the end of this
chapter.
The number of DMA channels is device-specific. Not all devices will implement all four channels. These devices will not imple-
ment all user interface registers. Unimplemented registers will always read as 0.
